What a little thinking shows….

These gender-disparity claims are also economically illogical. If women were paid 77 cents on the dollar, a profit-oriented firm could dramatically cut labor costs by replacing male employees with females. Progressives assume that businesses nickel-and-dime suppliers, customers, consultants, anyone with whom they come into contact—yet ignore a great opportunity to reduce wages costs by 23%. They don’t ignore the opportunity because it doesn’t exist. Women are not in fact paid 77 cents on the dollar for doing the same work as men.

Far too many policy proposals are premised on the absurd notion that privately available profit opportunities exist but remain unnoticed by all but professors, politicians, pundits, and preachers.

Café Hayek

Notice it is still possible for women to be paid, on average, less than men… but not for the same work under identical conditions,
